I am on version 1.70 and when I try to browse directories, I get the following errors: HTTP/1.0 500 Perl execution failed Server: MiniServ/1.700 Date: Wed, 13 Aug 2014 02:22:47 GMT Content-type: text/html; Charset=iso-8859-1 Connection: close Error - Perl execution failed Undefined subroutine &main::quote_javascript called at /usr/share/webmin/chooser.cgi line 192. I need help to fix this problem. Thanks!
